While the first episode did hype me up, it does go down till the finale.
I would have know more about their past, I would have skipped the assistants love interest and I would concentrated more on charater growing because this series was so short and had too much unnecessary stuff in it, it does not explain Miyatas change very well. The chemistry between the grown up leads was medicore at best, the "young" ones had a more believable chemistry imho. Senpai did well, but Miyata lacked a lot. Also the kissing and "hot scenes" were not that believable for me.
While production value was good, the story and it's execution lacked too much for me, which makes me disappointing in this japanse BL. It's not bad, but it could have been so much more.
